Some implementations of the bitcoin client also maintain a UTXO database or UTXO pool, which is the set of all unspent outputs on the blockchain. Although the name “UTXO pool” sounds similar to the transaction pool, it represents a different set of data. Unlike the transaction and orphan pools, the UTXO pool is not initialized empty but instead contains millions of entries of unspent transaction outputs, including some dating back to 2009. The UTXO pool may be housed in local memory or as an indexed database table on persistent storage. In response to a getdata message from the node, peers will send a merkleblock message that contains only block headers for blocks matching the filter and a merkle path for each matching transaction.
In 2017 and 2018, bitcoin’s acceptance among major online retailers included only three of the top 500 U.S. online merchants, down from five in 2016.

Any input satoshis not accounted for in the transaction outputs become the transaction fee. The bloom filter is initialized so that the array of bits is all zeros. To add a pattern to the bloom filter, the pattern is hashed GALA by each hash function in turn. Applying the first hash function to the input results in a number between 1 and N. The corresponding bit in the array is found and set to 1, thereby recording the output of the hash function.

A small percentage of the nodes on the bitcoin P2P network are also mining nodes, competing in the mining process, validating transactions, and creating new blocks. Various large companies interface with the bitcoin network by running full-node clients based on the Bitcoin Core client, with full copies of the blockchain and a network node, but without mining or wallet functions. These nodes act as network edge routers, allowing various other services to be built on top. As of 2018, the overwhelming majority of bitcoin transactions took place on cryptocurrency exchanges, rather than being used in transactions with merchants.
